Homemade electrodes made of putty capture heart data as well as some commercial devices

Researchers have found that homemade play-putty can effectively capture electrocardiogram (ECG) signals at a level comparable to commercially available electrodes. The play-putty is made with a simple mix of flour, water, salt, cream of tartar and vegetable oil—but the potential is much more than one may expect.

The putty, made with basic ingredients found around the house, can effectively capture ECG measurements.
